OWC 128GB DDR4 2933MHz ECC RDIMM

This OWC module provides 128GB of DDR4 ECC registered memory rated at 2933MHz with CL21 latency. It uses a 288-pin RDIMM form factor and operates at 1.2V. The kit is validated for Lenovo ThinkAgile HX series servers running Xeon SP Gen 2 processors.

Suited for ThinkAgile HX server upgrades

It fits Lenovo ThinkAgile HX2320, HX2321, HX3320, HX3321 and HX3520-G systems requiring registered ECC memory. It will not work in standard desktop computers or any platform that uses unbuffered DIMMs. Buyers needing non-ECC or consumer memory should look elsewhere.

Simple DIMM installation with one restriction

Installation follows standard server DIMM procedures: power down, open the chassis, align the notch and press until the latches click. The module cannot be mixed with unbuffered memory in the same system. Backward compatibility covers 2133MHz, 2400MHz and 2666MHz speeds.

Questions about this item

Which Lenovo ThinkAgile servers support this 128GB DDR4 2933MHz ECC RDIMM?

It is validated for ThinkAgile HX2320, HX2321, HX3320, HX3321 and HX3520-G running Xeon SP Gen 2 processors.

Can I mix this registered ECC module with unbuffered DDR4 DIMMs already in my server?

No. Registered ECC memory cannot be mixed with unbuffered modules; all slots must use registered ECC DIMMs.

How do I confirm the module runs at 2933MHz after installation?

Check the BIOS memory information or OS tools such as dmidecode; they should report 2933MHz (PC4-23400) at CL21 1.2V.
